Old Blues won 4-2 in round one but Cambridge will be a tougher proposition this time.
After watching his side lose narrowly in their first pre-season game, newly appointed Rotorua United coach Shaun McIlwaine told the Rotorua Daily Post "this side won't be relegated".
But time is running out for the prediction to become reality and tomorrow they host AFC Fury who won their first encounter 7-1.
United is in dire trouble and with their reserve side bottom of division two it is looming as a season of gloom.
Last week United showed some grit but still lost to Ngongotaha, another meritorious loss tomorrow will not be enough.
In other games, Tauranga City will be expected to beat Otumoetai, Whakatane Town will be favoured over Matamata Swifts, while it's a toss of the coin to predict the outcome of the Taupo Waikato Unicol clash.
Division two games tomorrow:
Rotorua United meet a strong Hukanui Rototuna side at Neil Hunt Park at 12.30pm, Matamata v West Hamilton, Old Blues v Cambridge, Papamoa v Tauranga Boys' Tokoroa v Tauranga City.
